ROSEHEAD Filed Feb. 26 1938 INVENTOR AAGE CHRISTIANSEN Patented Dec. 24, 1940 ROSEHEAD Aage Christiansen, Aalborg, Denmark Application February 26, 1938, Serial No. 192,864 In Denmark March 20, 1937 4 Claims.

The hitherto known roseheads, used for douches, involve the drawback that the passages for the water will soon be partly or entirely choked by impurities in the water, which will make the flow of the water difiicult, so that the jets of water on leaving the rose can scatter in wrong directions and strike outside the intended field. It has been attempted to remedy this choking of the holes by means of a series of pins fixed on a plate inside the rose, the conical tips of which pins enter into the passages of the rose, when the admission of the water to the rose is closed. This measure can to some extent prevent the choking of the holes by the smaller impurities contained in the water, but the pins hitherto known cannot prevent the larger particles contained in the water from embedding around the pins and then, when the pins are pulled away from the holes, follow the water and cover the holes. The said drawbacks have been removed in the present invention, which relates to a rosehead, in which a series of pins fixed on a plate, which is placed movably in the rose, pass out through the holes of the rose, by which any choking is prevented and, at the same time, the pins guide the jets of water outside the rose, so that the jets of water will only strike inside the intended field.

In the drawing:

Fig. 2 shows a section on the line a--a in Fig. 1.

l is a housing, which can be screwed on to a water line. At the bottom, the housing is closed by a plate 2, which by a screw ring 3 is fastened to the housing. On the plate 2 is fixed a pivot 4, on which is fixed a plate 5. At the top of the housing two plates 6 and 1 respectively are movably mounted on the pivot 4, between which plates the heads of a series of pins are held. The plate 2 has a series of holes 9, through which the pins 8 can pass out. The holes 9 are slightly larger than the pins. Between the plates 5 and 6 are placed springs l0, under the influence of which the plates 6 and I with the pins 8 are kept raised, when the admission for the water to the rose is closed. A cone stump I l is mounted in the upper part of the housing I to close the admission port. It is held in closed position by the springs Ill, urging plates 6 and 'l upwardly. The stump H is loosely positioned in the socket la provided therefor in housing I and is axially slidable therein. The diameter of cone stump II is less than that of recess la, so that when the conical surfaces of the stump and socket are separated the water will flow between the cylindrical walls of the stump II and socket la. A recess Ha is provided in the bottom of the cone stump to avoid engagement with the fixed pivot 4 when the cone stump is moved downwardly by the entrance of water into the housing I. When the admission for the water is opened, the water will press the plates 6 and l downwards, pressing first on the cone-stump ll. Thereby the pins will be pressed out through the holes 9. The ends of the pins 8, projecting outside the plate 2 when the plates 6 and 'l are pressed downwards, guide the jets of the water, so that they are kept in fixed directions.

I claim:

1. A rosehead comprising a cylindrical housing having an inlet at one end and a perforated discharge plate at the other end, a pin-supporting plate mounted in and spaced at its periphery from said housing for axial movement toward said perforated plate under the action of the pressure of water introduced into said housing through the inlet, a plurality of pins extending downwardly from said supporting plate through the perforation in said perforated plate, and resilient means urging said pin-supporting plate away from the perforated plate.

2. A rosehead comprising a cylindrical housing having an inlet at one end and a perforated discharge plate at the other end, a pin-supporting plate mounted in and spaced at its periphery from said housing for axial movement toward said perforated plate under the action of the pressure of water introduced into said housing through the inlet, a plurality of pins extending downwardly from said supporting plate through the perforation in said perforated plate, resilient means urging said pin-supporting plate away from the perforated plate, and means for guiding said pins and limiting the movement of the pinsupporting plate toward the perforated plate.

3. A rosehead comprising a cylindrical housing having an inlet at one end and a perforated discharge plate at the other end, a perforated pin-carrying plate mounted in said housing for axial movement, a plurality of pins having heads at one end and extending through the perforatioris of said carrying and discharge plates, a follower plate positioned on the upper side of said carrying plate and movable with and cooperating with said carrying plate to grip the heads of said pins to cause said pins to be displaced with said carrying and follower plates, and means resiliently urging said carrying and follower plates up toward the inlet end of the casing, said carrying,

guide and follower plates having their peripheries spaced from the housing.

4. A rosehead comprising a cylindrical housing having an inlet at one end and a perforated discharge plate at the other end, a stud fixed to the discharge plate and extending toward the other end of the casing, a guide plate fixed to said stud, pin-carrying and follower plates mounted on said stud for axial movement, said pin-carrying and 10 guide plates having perforations in register with
